My shed roof caved in last week and I learned a hard lesson about snow load
I built my backyard shed 3 years ago in Buffalo, New York, and never thought about how much snow it could hold. Last Tuesday we got a foot of heavy wet stuff and I heard this loud crack around midnight. Went outside with a flashlight and the whole roof had buckled inward, splitting the plywood right down the middle. Turns out I used 2x4 rafters on 24 inch centers, which is way too weak for the snow we get here. Now I'm tearing it down and rebuilding with 2x6 rafters on 16 inch centers, plus a steeper pitch. Has anyone else had a roof fail on a backyard structure, or am I just the unlucky one who skipped the load calculations?
